Term Paper Project: Designing a Secure Network
Due Week 10 and worth 190 points
This term paper involves putting together the various concepts learned
throughout this course. You are tasked with designing the most secure
network possible, keeping in mind your goal of supporting three (3) IT
services: email, file transfer (centralized), and VPN. Your first step is to
design a single network capable of supporting there three (3) different
services. Once you have fully designed your network, you will need to
provide three (3) workflow diagrams explaining how your designed
network handles the three (3) different transactions. The first is an
internal user sending an email using his / her corporate email address to
a user on the Yahoo domain with an arbitrary address of
user534@yahoo.com. The second workflow diagram should show a user
initiating an FTP session from inside your network to the arbitrary site
of ftp.netneering.com. The third workflow is an externally located
employee initiating a VPN session to corporate in order to access files
on the Windows desktop computer, DT-Corp534-HellenS, at work.
Write a ten to fifteen (10-15) page paper in which you complete the
following three (3) Parts. Note: Please use the following page
breakdown to complete your assignment:
2. Overall network diagram: One (1) page
Datapath diagrams: Three (3) pages (one for each diagram)
Write-up: six to ten (6-10) pages
Part 1
Using Microsoft Visio or its open source alternative, create a diagram
showing the overall network you’ve designed from the user or endpoint
device to the Internet cloud, and everything in between, in which you:
Authentication server (i.e. Microsoft Active Directory)
Routers
Switches (and / or hubs)
Local users
Remote users
Workstations
Files share (i.e. CIFS)
Mail server
Web servers (both internal and external)
Firewalls
Internet cloud
Web proxy
Email proxy
FTP server (for internal-to-external transport)
3. Explain each network device’s function and your specific configuration
of each networking device.
Design and label the bandwidth availability or capacity for each wired
connection.
Follow the access, core, distribution layer model.
Include at a minimum:
Part 2
Using Microsoft Visio or its open source alternative, create a Datapath
Diagram for the following scenario:
Local user sends email to a Yahoo recipient. Local (corporate) user
having email address jonny.hill@Corp534.com sends an email to
user534@yahoo.com.
Document and label the diagram showing protocols and path of the data
flow as data traverses through your network from source to destination.
Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5,
6, and 7 (OSI) protocols that are used for each flow.
Show user authentication when necessary.
Using Microsoft Visio or its open source alternative, create a Datapath
Diagram for the following scenario:
Local user, Jonny Hill, transfers file using ftp through the Internet to
another company’s site (ftp.netneering.com). He has to access the secure
shell using his active directory credentials to authenticate to the ftp
server (linux running Redhat) on the DMZ. He needs to transfer files
from his desktop across the Internet toftp.netneering.com.
4. Document and label the diagram showing protocols and path of the data
flow as data traverses through your network from source to destination.
Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5,
6, and 7 (OSI) protocols that are used for each flow.
Show user authentication when necessary.
Using Microsoft Visio or its open source alternative, create a Datapath
Diagram for the following scenario:
Remote user, Hellen Stover, connects via VPN from home through the
Internet to her corporate desktop, DT-Corp534-HellenS. Hellen uses a
browser to initiate her VPN connection. By browsing
tohttps://VPNaccess.corp534.com, she arrives at a login page where she
needs to authenticate using her Active Directory credentials before the
VPN tunnel is built.
Document and label the diagram showing protocols and path of the data
flow as data traverses through your network from source to destination.
Include path lines with arrows showing directions and layer 1, 2, 3, 4, 5,
6, and 7 (OSI) protocols that are used for each flow.
Show user authentication when necessary.
Explain how your overall design protects the organization from both
inside and outside attacks. Give examples.
Explain how your layered design compensates for possible device
failures or breaches in network security.
Determine whether any possible bottlenecks exist in your design.
Explain how to make the file transfer process more secure.
Part 3
5. Use at least three (3) quality resources in this assignment.Note:
Wikipedia and similar Websites do not qualify as quality resources.
Your assignment must follow these formatting requirements:
Be typed, double spaced, using Times New Roman font (size 12), with
one-inch margins on all sides; citations and references must follow APA
or school-specific format. Check with your professor for any additional
instructions.
Include a cover page containing the title of the assignment, the student’s
name, the professor’s name, the course title, and the date. The cover
page and the reference page are not included in the required assignment
page length.
Include charts or diagrams created in Visio or an equivalent such as Dia.
The completed diagrams / charts must be imported into the Word
document before the paper is submitted.
The specific course learning outcomes associated with this assignment
are:
Explain the essentials of Transmission Control Protocol / Internet
Protocol (TCP / IP) behavior and applications used in IP networking.
Identify network security tools and discuss techniques for network
protection
Describe the foundational concepts of VPNs.
Design a secure network to address a business problem.
Use technology and information resources to research issues in network
security design.
6. Write clearly and concisely about Advanced Network Security Design
topics using proper writing mechanics and technical style conventions
